American Robin foraging on the lawn in front of the National Gallery. 31 March 2010.

There are three different songs here sung by a Western Meadowlark. The first repeats three times, the second song repeats 4 times, and the third song is repeated three times. This was recorded on Marble Hot Springs Road at the 2nd 90 degree turn as the Meadowlark sang from the telephone wire above. In the background you will hear cows moo and a few other birds call as well, but the Western Meadowlark is clearly the focal subject of the recording. This was recorded with a Fostex FR-2 and Sennheiser shotgun microphone, ME66. The photo attached is a spectrogram of Western Meadowlark made in Raven Pro. (taxonomy:binomial="Sturnella neglecta")
